GO Bananamon!
-a huge increase in snatchable monkeys
-a wonderfully humorous new plot and settings
-new monkey costumes and the way they relate to the current stage of the game (Titanic monkeys jack and rose ^_^)
-new morph mode
-and slightly better graphics
-2 playable characters
-new fun minigames
and best of all.... MONKEYS!!!!
really, the only problem i had with it is that they didn't translate most of the monkey's names which was one of the more amusing parts of the earlier ape escapes.
and there are no proper camera control except for the 1st person point of view.
so, if you are a fan of monkeys and the series, definately give this one a try.
but if you are not, try it anyways, because it is a great puzzle/platformer/adventure type game with loads of stuff to fiddle with to keep you i nterested!
